What is the reaction between HCl and NaOH?
The reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) is a neutralization reaction which results in the formation of a salt, sodium chloride (NaCl) , and water (H2O) . It is an exothermic reaction.
What is the product of NaOH HCl?
The products are the water and salt, since they have been created following the reaction. For instance, in the equation HCl + NaOH → NaCL + H2O, the HCl (hydrochloric acid, a strong acid) and NaOH (sodium hydroxide, a strong base) are the reactants.
What is the balanced equation for Na h2o NaOH h2?
Balanced equation: 2Na+2H2O→2NaOH+H2 A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
Is the neutralization of HCl and NaOH exothermic?
The reaction of HCl(aq), a strong acid, with NaOH(aq), a strong base, is an exothermic reaction. The big idea for most calorimetry themed demonstrations is energy is conserved.
How do you neutralize HCl with NaOH?
Slowly add hydrochloric acid to a container of cold water to form a 1:10 dilution of acid to water. Slowly add a 1M potassium hydroxide, sodium hydroxide, or sodium carbonate solution until the pH is in the range of 6.0 to 8.0. Flush down the drain with an excess of cold water.
Is HCl an acid or base?
According to Arrhenius theory, a compound which when dissolved in water dissociates and furnishes H+ ions is an Arrhenius acid. According to Bronsted-Lowry theory of conjugated acid-base pairs, the H3O+ forms a conjugate base which is water (weakly basic). So HCl is a Bronsted acid because it donated an H+ to water.
Is NaCl an acid or base?
A salt that is derived from the reaction of a strong acid with a strong base forms a solution that has a pH of 7. An example is sodium chloride, formed from the neutralization of HCl by NaOH. A solution of NaCl in water has no acidic or basic properties, since neither ion is capable of hydrolyzing.
Is the equation NA h2o NaOH h2 balanced Why?
Since the number of atoms is equal on both the side of the equations, the given chemical equation is balanced.
What is the enthalpy of neutralization of HCl and NaOH?
For example, one source which gives the enthalpy change of neutralisation of sodium hydroxide solution with HCl as -57.9 kJ mol–1, gives a value of -56.1 kJ mol–1 for sodium hydroxide solution being neutralised by ethanoic acid.
What is the heat capacity of HCl?
Subtraction gives the mass of the HCl solution. The specific heat of 1 M HCl solution is 4.04 J/g•°C.
